- Creating a custom shader in Three.js to simulate a foil sticker effect with iridescence and metallic flakes.
- Iridescence is simulated by mapping view angle to hue, creating dynamic color shifts.
- Foil flakes are generated using procedural noise to create randomized sparkles.
- The implementation combines vertex and fragment shaders to handle peel geometry, lighting, and reflections.
- Vertex shader manages peel geometry, rotation, and ambient occlusion.
- Fragment shader handles lighting, reflections, iridescence, and foil flakes.
- The shader uses environment maps, Fresnel effects, and procedural noise for realistic results.
